They have been for a long time. If they have soft rubber eye cups you fold them down, so you can place your glasses very close to the lens.
I prefer the harder rubber ones that pop or screw up and down.
You can also leave the cups up and focus the binoculars to your vision with out glasses. I am not sure of the range of the focus, I am near sighted, needing corrective to pass the eye test at the Dept. of Motor Vehicle and I can focus my binoculars with and without glasses.
